Ubuntu Security Notice USN-5855-3
March 31, 2023

imagemagick regression
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 22.10
- Ubuntu 22.04 LTS
- Ubuntu 20.04 LTS

Summary:

USN-5855-1 introduced a regression in ImageMagick.

Software Description:
- imagemagick: Image manipulation programs and library

Details:

USN-5855-2 fixed vulnerabilities in ImageMagick. Unfortunately an additional
mitigation caused a regression. This update fixes the problem.

We apologize for the inconvenience.

Original advisory details:

 It was discovered that ImageMagick incorrectly handled certain PNG images.
 If a user or automated system were tricked into opening a specially crafted
 PNG file, an attacker could use this issue to cause ImageMagick to stop
 responding, resulting in a denial of service, or possibly obtain the
 contents of arbitrary files by including them into images.

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 22.10:
  imagemagick                     8:6.9.11.60+dfsg-1.3ubuntu0.22.10.4
  imagemagick-6.q16               8:6.9.11.60+dfsg-1.3ubuntu0.22.10.4
  libmagick++-6.q16-8             8:6.9.11.60+dfsg-1.3ubuntu0.22.10.4
  libmagickcore-6.q16-6           8:6.9.11.60+dfsg-1.3ubuntu0.22.10.4
  libmagickcore-6.q16-6-extra     8:6.9.11.60+dfsg-1.3ubuntu0.22.10.4

Ubuntu 22.04 LTS:
  imagemagick                     8:6.9.11.60+dfsg-1.3ubuntu0.22.04.3

  libmagickcore-6.q16-6-extra     8:6.9.11.60+dfsg-1.3ubuntu0.22.04.3

Ubuntu 20.04 LTS:
  imagemagick                     8:6.9.10.23+dfsg-2.1ubuntu11.7
  imagemagick-6.q16               8:6.9.10.23+dfsg-2.1ubuntu11.7
  libmagick++-6.q16-8             8:6.9.10.23+dfsg-2.1ubuntu11.7
  libmagickcore-6.q16-6           8:6.9.10.23+dfsg-2.1ubuntu11.7
  libmagickcore-6.q16-6-extra     8:6.9.10.23+dfsg-2.1ubuntu11.7

In general, a standard system update will make all the necessary changes.
